JOHN ANSTY, OF LANS- APPARATUS FOR SIZING BARRELS.

SPECIFICATION forming part of Letters Patent No. 396,370, dated January 15, 1889.

Application filed A t 25, 1888. Serial No. 283,755. (No model.)-

To all whom it may concern:

Be it known that I, THOMAS ROBERTS, a citizen of the United States, and a resident of Philadelphia, Pennsylvania, have invented certain Improvements in Apparatus for Sizing Barrels, of. which the following is a specification.

The object of my invention is to thoroughly and quickly size the interior of barrels, espe- IO cially such as are used for the transportation of oil.

In the accompanying drawings, Figure 1 is a side View of the device which I employ in carrying out my invention. Fig. 2 is a plan I 5 View of the same, and Figs 3, l, and 5 are transverse sectional diagrams showing a barrel in the different positions which it assumes during the sizing operation.

Barrels used in the transportation of many liquids, especially those used for petroleum,

must be sized with glue or other suitable material before they are filled, otherwise the oil will penetrate the wood of the staves and heads or find its way through minute inter- 2 5 stices in the barrel, and the latter will consequently leak. I so construct the skid by which the barrels are transferred from the gluing-stand to the filling-stand that the barrel will be automatically vibrated as it rolls along 0 the skid, and the thorough distribution of the sizing-liquid in the barrel will be insured.

A A are the side rails of the skid, secured together in any suitable mannerin the present instance by bolts B. The side rail, A, of

5 the skid is recessed at a, and the rail is inclined at each side a a of the recess (1, while the rail A is recessed at l) and inclined at each side I) Z) of said recess.

The recess in the rail A is opposite to the highest portion of. the rail A, and correspondingly the recess in the rail A is opposite the highest portion of the rail A. Consequently if a barrel is rolled along the skid in the direction of the arrow, Fig. 1, it will first assume the horizontal plane shown in Fig. 4, with the sizing, as shown. hen the barrel reaches the recess a, one end of the barrel will enter the recess, thus causing the tilting of the barrel, as shown in Fig. 3, and the sizing will flow toward and rise past the center of the head (Z of the barrel, and consequently size the interior of the head. When. the barrel reaches the point as, Fig. 1, it will be midway between the two recesses a Z), and will again assume the horizontal position shown in Fig. 4, after which it will again dip, but in the opposite direction, as shown in Fig. 5, the sizing being washed against the head 9 of the barrel, so that by the time the barrel passes the second recess, 1), its interior will be completely 6o coated with the sizing material, and it is ready to be passed to the fillers. During the passage of the barrel over the skids the inspector can stand at one side and detect any leak in the barrel, and can either stop the barrel at any point along the skid and plug the hole or chalk the opening for subsequent attention,

as circumstances suggest.

The recesses need not be as long as shown in the drawings, but may be made short, and two or more recesses may be made in each skid, the character of the skid depending altogether upon its length. If, fori nstance, the space is contracted the recesses may be contracted; but if the space is not limit-ed the skid can be of any desired length, and the re ecsses can be made in proportion.

The skid may be tilted, if desired, so as to increase the speed of the barrel; but I have found by experiment that by giving the barrel a push after the sizing material has been inserted and the barrel corked it will have sufficient momentum to reach the opposite end of the skid.

I claim as my invention A pair of skids for sizing barrels, said skids having side rails with recesses out of line with each other, substantially as described.

In testimony whereof I have signed my name to this speci fication in the presence of two sub- 0 scribing witnesses.

THOMAS ROBERTS.
